The capacitor containing an ebony case, and the knob made from an ebony new release

 At our company, I decided to put the film capacitor containing an ebony case, and the knob made from an ebony on the market lately.
Although the capacitor containing an ebony case was used for the inside of the amplifier of our company from the former, since the sound quality improvement effect was large, I did it to considering it as those for its original work audiophiles lately, and starting general sale.
Having become a cause which uses the capacitor containing an ebony case in our company goes back, when the polycarbonate capacitor has already been put on the market from Soshin Electric 20 years or more ago.
Sound quality of polycarbonate surpassed than the film capacitor of others capacitor.
When the cause was explored, I judged that it was a factor of the improvement in sound quality that the case was somehow filled up only with the polycarbonate capacitor.
Then, as a result of making the capacitor containing a plastic case, and the capacitor of the product made from an ebony entering a case as an experiment in our company, when the case of the Africa ebony used for oboe, a clarinet, etc. was filled up with a capacitor, it turned out that it is said that the best sound is obtained.
A film capacitor vapor-deposits metal, such as aluminum, on a thin film, it is rolled round, and it hardens it, and makes it the capacitor.
From the former, the round form film capacitor has been most said for sound to be good and for neither the thing which was crushed to the ellipse, nor the thing which became a square shape to have a good sound.
Since vibration of a film film has few round shapes, it is indifferent.
If saying suppresses vibration of the film to a limit, it will also be saying that sound quality improves further.
About 1.4 has specific gravity and, as for a material which is used at our company and which is called the Africa ebony, the vibration control effect is accepted also as bases for amplifier or speakers.
Into the ebony case, the capacitor is filled up with our company using the most excellent epoxy resins, such as an electrical property and intensity.
Vibration by a music signal was suppressed by this and sound quality of a capacitor element improved greatly by it.
As an element for the capacitors containing an ebony case, I have adopted the polypropylene capacitor made from U.S. Dearborn.
Dearborn is the company which the section which was manufacturing the film capacitor of the old, famous Sprague company became independent of.
For the reason, I excelled in the production technology of the film capacitor, and checked the sound quality which was most excellent in comparison with the other company.
At our company, a polypropylene capacitor called 735P type is mainly adopted out of the many products of the Dearborn.
When this 735P type is used for a power supply circuit etc., it can respond to big ripple current and a quick current response is the feature.
Of course, when it is used as a coupling capacitor, we demonstrate the low rate of distortion.
Although we sell the capacitor of four kinds of entering an ebony case at our company
I recommend you to use 0.47 micro falad and 1 micro falad of objects for the coupling capacitors of amplifier, and to use the object for the cathode bypass capacitors of vacuum tube amplifier and 2 micro farlad 10-micro falad as a filter capacitor of a power supply.
When Kem Cong is used as contest a filter within the amplifier of the present use, it is effective even if it uses it for the capacitor, carrying out Paralel attachment.
If it can do and contest a filter of a power supply is constituted only from an ebony capacitor by the device of a circuit, an effect will become large most.
Although a coupling capacitor is also effective, at our company, we recommend you use in a power supply circuit.
You could realize saying whether sound changes like this by a power supply circuit.

Although the knob made from an ebony is the thing which is also using this for our products, it is a knob which deletes the Africa ebony used for oboe or a clarinet and which was taken out and made.
Although metal knobs are common, a warm almost deep-black knob will become an accent of its original work amplifier.
